i FFIQCE Application MarchZ, 1938, |Serial No. 193,454 n z claims. (01.221454) y 'Ihis invention relates to closures for containers 'I such as bottlesand the like.

device embodying this invention with the It is an object of this invention to provide a twopiece-closure whichA will be simple in construction and which nevertheless will maintain a tight joint at all times. o

Other objects of the invention `will in part be obvious and will in part appear hereinafter.`

The invention accordingly comprises an article of manufacture possessing the features, properties, and the relation of elements which` will be lexemplied in the article hereinafter described and the scope of the application of .which will `be indicated in the claims. A

For a fullerunderstanding of the nature and objects of the invention, reference should be had to the following detailed description, taken in connection with the accompanying drawings, in which:

Figure 1 is a plan view partly in section to a K parts shown in closed position.

Figure 2 is a central section therethrough.

Figures 3 and 4 are similar to Figures 1 and 2 except that they show the device in the open position. v

Figure 5 is a central section through a modified form of the device.

Figure 6 is a. top plan view, parts being broken away, of a third embodiment with the closure open.

Figures '7 and -8 are central sections through the closure of Figure 6, Figure 'l showing the closure closed and Figure 8 showing the closure open.

Figure 9 shows a top plan view, `parts being broken away, of a fourth embodiment.

Figure 10 is a central section showing the closure open.

Figure 11 is a gure similar to Figure 10, with the closure in closed position.

In the drawings the numeral I0 designates a base portion having a circumferential wall II and an end wall I2, such end wall being provided with an opening I3, which opening is completely surrounded by a raised portion I4. Upon the base lthere is mounted a cap I5 rotatable upon the base and retained upon it by a bead I 6 in` the base, mating with a bead I'I in the cap.

Upon one of these members, as preferably upon the base portion there is formed, on the side opposite the opening, a raised portion IB as high or slightly higher than the raised portion I 4.

The cap itself has an end wall ill provided with an opening corresponding in size, shape and position tothe opening I3 and, if desired, this opening 20 may also have a depressed portion 2l immediately surrounding theopening 20 so as to make a tight joint with the raised portion I4 of the opening I3 when the cap is in closed position. In order lto .provide a` tight closure when the capy i is closed, the endwall I9 has an imperforate de#- pression 22.of size and :shape to comeinto regisl try with the raised portion Il 'around the` opening I3 when` the cap is in closed position. As `Will be understood any convenient means may be provided for limiting the rotation of the cap so that it will move only between the fully closed position and the, fully `open position. As illustrated this may take the form of depressions 23 and 24 in the cap, positioned so `that one of them will engage one side ofthe raised yportion I5 when the cap is fully o'pen' and the other` will'engage the other side of the raised portion I5 when the cap is fully closed.

In the form oi' the invention shown in Figure 5, the raised portion I4 around the opening I3 is provided by means of an inset washer of cork or other suitable composition. The end wall I2 of the member I I being depressed to receive the said washer.

In Figures 6, 7 and 8, the invention is shown as embodied ina side opening turret top, the breast of the container is 'provided with a cylindrical dome 3 I having an imperforate end 32 and a side cylindrical wall provided with an opening 33. Completely surrounding the opening 33 is a raised portion having its 'extreme peripheral edges iiat to provide a bearing surface for the cap. A cap 35 ts completely over the dome and has an opening 36 adapted to be brought into and out of registry with the openingi 33 by rotating the cap;

The dome and the cap are provided with mating .bearing surfaces to hold the cap for rotation and prevent tilting or movement in either direction along the axis of the dome. As shown, the dome is provided with a peripheral rim 31 iltting into a corresponding groove in the interior of the cap. The outer face of the cap 38 may be left open or closed, as desired. In the drawings it is shown as open.` A projection 39 extending outwardly 'from the side of the base on the side opposite the opening 33 bears against the cap to help retain it in place to assist in holding the opening 36 tightly against the raised portion 3l.

In Figures 9, 10 and 11 the invention is shown as embodied in a sifter top in which the dome l0 on the breast of the container is providedwith a plurality of openings 4I arranged in circular form about the center, each opening having a 2liA be said to fall therebetween.

naised surface l2 completely surrounding its periphery. A cap 43 flts over the dome 40 and has a circumferential bearing surface 44 adapted to engage all of the bearing surfaces 42 in all positions of the cap. The cap 'is provided with openings through the bearing surface 45 which, in one position of the cap, are designed to mate I with the openings Il and to give a considerable amount of resilient pressure between the bearing surface M and the surfaces I2. Each of the peripheral edges of the cap slopes upwardly and away from the openings 45, making the outer face of the cap concave with the openings at the bottom of the concavity. In this embodiment the bearing surfaces between the cap and the dome are formed by providing a shoulder 46 upon the dome over which is formed an internal peripheral projection 4l on the cap.

In any of these embodimentsrof the invention there is provided a two piece top of economical construction which will give a tight closure and which is of neat appearance and rugged construction.

Since certain lchanges may be made in the above construction and different embodiments of the invention .could be made without departing from the scope thereof, it is intended that all matter contained in the above description or shown in the accompanying drawings shall be l interpreted as illustrative and not in a limiting sense. t

It is also tobe understood that the following claims are intended to cover all of the generic and specific features of the invention hereinfdescribed, and-all statements of the scope of the invention, which as a matter of language, might position.

Having' described` my invention,.what I claim as new and desire to secure by Letters Patent is:

1. A closure for containers and the like comprising abase portion, a cap rotatable upon said base portion, there'being openings in said cap 5 and base portion between the center and the periphery adapted to be moved into and out of registry by rotation of the cap, confined to an arcuately narrow area of the base and a raised portion upon the base immediately surrounding l the opening inthe base for localizing the contact between the base and the cap, of such size and shape as'to effect a tight joint in both the open and clos'ed positions and imperforate inter-engaging surfaces disposed diametrically from said l openings for preventing tilting of the cap.

2.- A closure for containers and the like comprising a base portion, a cap rotatable upon said base portion, there being openings in said capand,

base portion between the center and the periphery adapted to be moved into and out of regis, try by rotation of the cap confined to an arcuately narrow area of the base and a raised portion upon the base immediately surrounding the I opening in the base for localizing the contact PERCY M. THoRN.
